Hi all we are in the process of migrating a SVN repository from Windows to Linux.
While experimenting how best to do this I have tried using both SVNADMIN DUMP / LOAD, SVNSYNC, and even SVNRDUMP. The resulting target repos have dramatically different sizes, hence this mail. Original repo size 5.51 GB Almost 19,000 revisions SVN version 1.5.1 FSFS Windows Server 2003 Target repo(s) SVN version 1.7.14 (r1542130) FSFS Oracle Enterprise Linux 7.0 In both cases SVN was installed as an executable (i.e. not compiled or modified by us). I first attempted a migration using SVNADMIN DUMP / LOAD. This gave me a dump file of 10.8 GB. However, as we encountered the" E125005: Cannot accept non-LF line endings in 'svn:log' property" error (more of which at the bottom of this mail), I also tried migrations using SVNSYNC and SVNRDUMP, as these tools should auto-correct the non LF line-endings. Migrating using SVNADMIN DUMP / LOAD, I get a target repo of 4.5 GB Migrating using SVNSYNC, I get a target repo of 149 MB! I have tried running SVNSYNC from the target machine (OEL 7.0), and from the source machine (Win 2003), and get the same result. SVNRDUMP also gives a repo of 149 MB To eliminate OEL 7.0 / SVN 1.7.14 as factors, I also did a test migration via SVNSYNC to SVN on an OEL 6.5 running SVN 1.6.11 (r934486). This gave a repo of 148 MB. So SVNADMIN gives me a 4.5 GB repo, which is close in size to the original repo size (5.51 GB), but SVNSYNC & SVNRDUMP give me 149 MB repos! Drilling down into the file system of the repos, I can see that: a) the revprops directories of SVNADMIN and SVNSYNC loaded repos are both 75MB b) the revs directories contain a similar number of files, but have significant size differences: 4.4G /svn_repos/repo_loadedby_svnadmin/db/revs 75M /svn_repos/repo_loadedby_svnsync/db/revs SVN LIST gives results for the repo loaded by SVNADMIN, but nothing for those loaded via SVNSYNC. Any ideas what is going wrong with SVNSYNC? Have I missed anything? I have googled myself to near death, but cannot find any similar reports. Thanks in advance for your help Chris Lamb IT Architect p.s, on the topic of E125005: The various sed based solutions suggested on http://stackoverflow.com/questions/10279222/how-can-i-fix-the-svn-import-line-endings-error did not work for me. The resulting file produced the same error. I did not want to use -bypass-prop-validation, as this just delays the problem until a later date. I ended up using the SVN 1.5.1 SVNSYNC (which also throws this error) to identify the affected properties, then corrected them via svn propedit, editing one property higher than the last revision reported. svn propedit svn:log svn://otms/repo_source --username XXXX --password xxxx --revprop -r 14928 In most cases, just saving the property "unchanged" in vi was enough to correct it. Having edited the property, I then rerun SVNSYNC until the next error ...
